What Makes Dyersburg's Water Unique?

Local geology and source profile

Source: GroundwaterTDS: 74 mg/LpH: 6.4

The Dyersburg Water Department serves around 19,759 people in Dyersburg, Tennessee, with groundwater treated at facilities using conventional filtration, pre-oxidation with chlorine, softening, and disinfection with hypochlorite. The water originates from the Eastern Highland Rim aquifer system, and a related entity, Dyersburg Suburban Consolidated Utility District, also provides water quality reports confirming compliance with EPA standards. The Dyersburg Water Department is located at 514 Fuller Road, PO Box 1358, Dyersburg, TN 38025, with an emergency line at (731) 285-4019.

The Eastern Highland Rim region features less mineral-rich sediments, such as sandstones and shales from Paleozoic formations, including the Ordovician and Silurian periods. This local geology contributes to lower concentrations of dissolved calcium and magnesium, distinguishing it from harder supplies in the Cumberland Plateau's karst limestone terrains. The area's faster-percolating sediments impart a softer water profile with reduced dissolved minerals.

When it comes to household appliances, the softer water profile in Dyersburg means you'll likely experience less mineral buildup in your water heater, dishwasher, and coffee maker, reducing maintenance needs and extending equipment life. Soap lathers efficiently without excess use, and skin dryness from showering is unlikely. Unless individual testing reveals specific concerns, a water softener is generally not recommended. Dyersburg's tap water earns an A grade, with no contaminants exceeding EPA maximum contaminant levels, though some exceed non-enforceable health goals - residents can contact the Dyersburg Water Department or test independently for reassurance.

Geology & Source: Eastern Highland Rim - Paleozoic sandstones and shales; lower mineral content due to less limestone

Frequently Asked Questions

Is Dyersburg's water safe to drink?
Yes. Dyersburg's water meets all federal safety standards. The hardness is 182 mg/L (Very Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.
Do I need a water softener in Dyersburg?
At 182 mg/L (Very Hard), Dyersburg's water will cause significant limescale on kettles, washing machines, and water heaters. A water softener or descaler is strongly recommended to extend appliance lifespan and reduce energy bills by up to 24%.
How does Dyersburg compare to the USA average?
The USA national average is 151 mg/L. Dyersburg (182 mg/L) is 31 mg/L above the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Dyersburg is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

Water Hardness

Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city β€” the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.

Estimated

pH

Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock β€” values may differ from utility-reported figures.

Estimated

TDS β€” Total Dissolved Solids

Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.

Measured

PFAS β€” Perfluoroalkyl and Polyfluoroalkyl Substances

EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) β€” sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.

Modelled

Lead

Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age β€” all estimates are maintained below the EPA action level of 0.015 mg/L.

Calculated

Appliance Lifespan

Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
